Why you should switch from a belt press to a centrifuge?

Centrifuges can sometimes achieve higher cake solids than the belt press filter with a low capture (or high polymer) dosage rate. This is due to the centrifuge's shearing ability as the sludge moves through the machine, while the temperature increase in the sludge from the power energy dissipated.
